The Supreme Court is set to weigh in on the complex issue of online sales tax collection. That is a bad idea. The correct venue to resolve this long-standing dispute continues to be the Congress.

The Supreme Court is no stranger to this issue. In fact, the last time it reviewed online sales tax collection, it explicitly found that Congress is the correct setting to address any changes to the current system.

Today, all websites and retail stores play by the same rules when it comes to sales taxes: They all collect and pay for each state where they have a business location. State tax authorities have tried to force out-of-state companies to collect sales tax, too.

For decades, they have petitioned Congress to change the rules. They have been unsuccessful for one simple reason: State tax collectors do not want to simplify their tax codes.

As a result, Congress has correctly concluded that forcing Internet retailers to collect sales tax for 9,600 taxing jurisdictions, each with its own rules, would result in undue compliance burdens and excessive liability.

In 2013, the Senate passed a bill that would have required online retailers to collect sales tax if they had at least $1 million in annual sales. This proposal ultimately died in the House. However, it was a missed opportunity for the states. Rather than working with all stakeholders to find a solution, they decided to pursue an alternative strategy designed to force the Supreme Court review.

Regardless of the outcome of this upcoming ruling, the issues of compliance and liability will not go away. There is no magic-wand solution that can mitigate the undue burden of mandated tax collection.

Convening all stakeholders to mediate a solution to this complex problem is a job best left to Congress. The Supreme Court has already tried to resolve this dispute twice before. It’s just not that simple.
